Nobel Prize for Promises?

I was dismayed when I heard Obama was given the Nobel Peace Prize. A shock, really, to think that a president carrying on wars in two countries and launching military action in a third country (Pakistan), would be given a peace prize. But then I recalled that Woodrow Wilson, Theodore Roosevelt and Henry Kissinger had all received Nobel Peace Prizes. The Nobel Committee is famous for its superficial estimates and for its susceptibility to rhetoric and empty gestures, while ignoring blatant violations of world peace.
